"If you openly say, 'here are three games to prove yourself' and one guy goes and blitzes it against the best bowlers in Australia, New South Wales, last week, then it is hard to say to him, 'nah, mate, you haven't done enough'," said Rogers.

"It is amazing what happens when that pressure goes on and you start thinking about selection."

Explosive opener Jake Weatherald (152, 160 balls) cracked his third ton across the first-class and one-day formats this season in SA's first innings at the WACA.

"It was an interesting thing for the selectors to do, throw it up there for anyone to do well. We have a couple of bolters," said Rogers.

Renshaw, 21, has 70 runs at 11.9 from six first-class digs this season. Selectors are set to unseat at least one of incumbent trio - 10-Test opener Renshaw, No.6 Glenn Maxwell and keeper Matt Wade. None has a compelling case for retention.

Callum Ferguson was a form candidate for Test recall at No.6 after an unbeaten 182 against Victoria but was run-out for 33 in Perth yesterday. SA finished 6/322 at stumps, 192 runs behind the Warriors' 7(dec)/514.

"Who is going to go to No.6? Now Matt Renshaw has failed again and I think Bancroft might sneak in," Rogers told SEN's The Run Home.

"None has done outstandingly," said Rogers. "To play at the highest level you need experience, to know when the chips are down how you react. That's why there are question marks over Renshaw," he said.
